Example 1

As shown in fig. 1-2, the invention provides a cooling tower with heat exchange devices, which comprises a tower body 1, and a filler 2, a spraying device 3, a water receiver 4, a plurality of heat exchange devices 5 and a plurality of air exhaust devices 6 which are sequentially arranged on the tower body from bottom to top; an air inlet is formed in the lower part of the tower body 1; the water collector 4 is used for preventing water splashing; the heat exchange device 5 is communicated with the spraying device 3; the number of the heat exchange devices 5 is the same as that of the exhaust devices 6, the installation position of each heat exchange device 5 corresponds to that of the exhaust device 6 one by one, and the plurality of heat exchange devices 5 and the plurality of exhaust devices 6 are arranged in a regular polygon manner; the heat exchange devices 5 are connected in parallel, water inlet and outlet loops can be respectively and independently controlled, and partial pipelines or all pipelines can be opened and closed under different environmental working conditions and different cooling temperature requirements.

Further, a cross beam is arranged in the tower body 1, a filler support frame is laid on the cross beam, and the filler 2 is placed in the filler support frame.

Further, the heat exchange device 5 is a fin tube heat exchanger and is horizontally arranged inside the tower body 1.

Furthermore, the cooling tower comprises four sets of heat exchange devices 5 and four sets of exhaust devices 6 which are arranged in a square shape, according to the arrangement mode, the size of the cooling tower monomer can reach the length and the width of between 30 and 40 meters, and the modular heat exchange devices connected in parallel are arranged, so that the limit of the processing capacity of the cooling tower monomer is greatly improved, and meanwhile, the zone control can be realized, and the more efficient and energy-saving operation mode can be realized.

When the motor runs in summer, the fan is fully opened, and the motor runs at full load. Circulating water firstly passes through the heat exchange device and then enters the spraying device to be sprayed to the filler, air enters from the air inlet at the lower part and flows upwards through the filler, the circulating water cooled by heat exchange of the filler flows into a water tank below the tower body after contacting and exchanging heat with the circulating water, then the air continuously passes upwards through the heat exchange device and carries out partition wall heat exchange with the circulating water, and because the heat exchange of the circulating water at the section is not directly contacted with the air, no evaporation loss and air blowing loss exist, and a certain water-saving effect is achieved.

In winter, two operation modes are provided, one mode is that the fan is fully opened, the motor runs in full load, all circulating water enters the heat exchange device for heat exchange and then enters the spraying device for spraying to the filler, and because the temperature is lower in winter, the temperature of the circulating water can reach lower outlet temperature when the heat load is unchanged; the other is that the fan is fully opened, the motor runs at full load, after all circulating water enters the heat exchange device for heat exchange, one part of circulating water is sprayed to the filler through the spraying device for heat exchange and finally falls into the water tank, the other part of circulating water is directly bypassed to the water tank, and finally the required cooling temperature is achieved. In winter, the most economical operation mode can be selected according to the requirement.

By adopting the cooling tower with the heat exchange device, the fans are respectively and independently arranged above the multi-module heat exchange device, so that the structure of the whole equipment is more perfect, the use strategy of water and energy conservation can be controlled according to the actual use condition, the heat transfer efficiency of the whole equipment is improved, the heat exchange requirement at higher or lower temperature is met, the possibility of scaling of the equipment is reduced to the minimum, the service life of the equipment is prolonged, and the operating cost is reduced.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
